Adding one or more Wideband Oxygen Controllers to your MegaSquirt ECU has never been this easy or accurate. MegaSpartan is the first Wideband O2 Controller that communicates directly with your MegasSquirt 2 or MegaSquirt 3 ECU over digital CAN bus.

Tune with the confidence that your AFRs are accurate, that noise and ground offsets are a thing of the past. 

Upgradability from a single Wideband O2 Controller to eight Wideband O2 Controllers means MegaSpartan will grow with your needs.

MegaSpartan is crafted with all automotive grade extended temperature components; -40[C] to 125[C], and is backed up with a warranty that is twice as long as any competing product, 2 years.
